Abstract :

The present paper deals with a modified ratio estimator for estimation of population mean of the study variable using the linear combination of Median and Co–efficient of Kurtosis of the auxiliary variable, with the intention to improve the efficiency of ratio estimator in simple random sampling. The first order approximation to the bias and mean square error (MSE) of the proposed estimator are obtained. Theoretically, it is shown that the proposed estimator performs better than the existing modified ratio estimators. In order to justify this, existing agricultural data set from censes 2001 was used which shows that the proposed modified ratio estimator is more efficient than the others.
